Answer:

700.4 cm

Step-by-step explanation:

This involves two similar triangles.

Both triangles are right triangles.

One has legs measuring 1 cm and 30 cm. We can find the hypotenuse by using the Pythagorean theorem.

(1 cm)^2 + (30 cm)^2 = c^2

c^2 = 901 cm^2

c = sqrt(901) cm

The second triangle has one leg with length 700 cm. This leg corresponds to the 30-cm leg in the other triangle. Since the triangles are similar, we can use a proportion to find the hypotenuse of the second triangle.

(30 cm)/(700 cm) = [sqrt(901) cm]/x

3/70 = sqrt(901) cm/x

3x = 70 * sqrt(901) cm

x = 70 * sqrt(901) cm/3

x = 700.4 cm

In the figure we have the graphic of this equation. So, the vertex is the maximum of this function. This point means that the maximum daily profit from soccer balls is:

 $y = 236.67$

And this happens when the selling price of each soccer ball is:

 $x = 8.33$

So if you want to get the best daily profit, this is the price you must sell each soccer ball.

Find the slope of the line that passed though the two points (0,5) and (-9, -4)

OverLord2011 [107]

To find the slope, use the slope(m) formula:

$m=\frac{y_2-y_1}{x_2-x_1}$ and plug in the two points

(0, 5) = (x₁, y₁)

(-9, -4) = (x₂, y₂)

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{-4-5}{-9-0}$

$m=\frac{-9}{-9}$ [two negatives cancel each other out and become positive]

m = 1 The slope is 1

What would you have to do to change 10 cubic feet into cubic inches?

Temka [501]

1 ft = 12 inches
(1 ft)^3 = (12 inches)^3
1 cubic foot = 1728 cubic inches

You'll multiply by the conversion factor (1278 in^3)/(1 ft^3) to convert from cubic feet to cubic inches. Notice how the cubic feet ft^3 unit is at the bottom of the conversion fraction, so that the cubic feet units cancel.

Answer: A) multiply by 1728
